An edge-illuminated transparent slab is optically joined over substantially its whole area to a light-reflecting faceted surface, the facets being illuminated in predetermined variable manner to give an effect of animation. The slab and reflective surface may be joined by a layer of glucose liquid, glycerol, liquid paraffin, plastics cement, or clear varnish, or by a sheet of transparent regenerated cellulose coated on each side with pressure adhesive, or the reflective surface may be dropped in a pocket of water on the rear face of the slab. The or each edge along which the slab is illuminated may be convex, or notched with a separate lamp opposite each notch, the lamps being lit sequentially. Alternatively continuously lit lamps may be rotated around the slab periphery, or continuously lit lamps or fluorescent tubes be placed around the slab periphery and an endless band with alternate transparent and opaque portions moved continuously either around the slab or the lamps.

[Also in Divisions B3, B5 and H2] A thermostatic capsule comprises two thin metal or plastic discs 1 and 2 electrically roller welded to each other along their peripherics 3, having annular ribs, and enclosing a substance 9 whose volume varies with temperature. No metal used may be nickel silver, steel, or steel alloy, e.g. 18/8 stainless steel for a disc 25 mm. in diameter, 0.1 mm. thick. The enclosed substance is chosen for the temperature range in which the device is to operate and may be "Freons" (Registered Trade Mark), butane, propane, acetone, ether or plastic mixtures; zinc or bismuth which sublime below 400‹C. may be used. A sudden capsule expansion at certain temperatures is achieved by deforming one of the discs, before or during assembly, beyond its elastic limit; this movement may be used to actuate an electrical switch. Measured quantities of fluid substances 9 may be used by charging a porous disc of blotting paper, synthetic sponge, cloth, or compressed fibre, with the fluid e.g. liquefied gas, and placing it between the cooled metal discs. Alternatively, a liquefied gas may be introduced while contained in a closed plastic bag which is subsequently ruptured. Capsules are made by clamping discs 1 and 2 and the enclosed thermometric substance 9 between hol-. low members 7 and 8 whose edges 7a and 8a fit the ribs. Milled rollers 10 and 11 then turn in opposing directions for the welding process.

Abstract: 1485673 Spindle mounting and driving HAMEL GmbH ZWIRNMASCHINEN 30 Oct 1975 [7 Nov 1974 15 Sept 1975] 44835/75 Heading DID A spinning or doubling spindle has a bearing 33 located in an eccentric sleeve 22 mounted for rotation in a bearing housing 16 such that rotation of the sleeve 22 in the housing 16 moves a spindle whorl 36 into and out of contact with a tangential drive belt 38. A torsion spring 28 biasses the sleeve into the drive position where it is located by a ball latch 40. Additionally a spring loaded telescopic device 52 is provided to hold the spindle in an engaged or disengaged position by an over centre action. On disengagement of drive, after the belt 38 and whorl 36 have lost contact, a stop 86, (Fig. 2), is engaged by a brake lever 80 to spread brake shoes 76 into engagement with a spindle skirt 72. Movement of operating lever 50 can be produced by actuators 134, 136 (pneumatic, hydraulic or electrical) in response to a full package or ends down stop motion which can also activate a yarn cutter. In an alternative embodiment the spindle is spring loaded to the disengaged position and held engaged by a latch. The latch can be released by a stop motion via a coaxial tube and cable device.

Title: Process and apparatus for continuously dehydrating air
IPC: F24F3/14
Filed: 1964-11-04
Abstract: Water vapour is removed from a gas, such as air, by passing the gas into a column of liquid having a viscosity of 40-5, 000 S.U.S. at -100 DEG F. - 40 DEG F. and a specific gravity less than ice, freezing the water vapour to form ice crystals which fall into a lower part of the column where melting takes place, collecting liquid water at the bottom of the column and withdrawing dry gas above the top of the column.  As illustrated in Fig. 1 (not shown) moist air is passed into the column of liquid in vessel 11 through sparger 13 and ascends into zone 16 cooled by liquid passing through coil 15 and controlled by valve 31 in dependance on the temperature in the zone. Ice crystals form and descend into zone 23 warmed by means of similarly controlled heating coil 22 where water forms and falls into the bottom of the vessel.  A mist collector 19 removes entrained liquid before the dry air is removed at 21.  The vessel is surrounded by insulating material 27.  Specified liquids are kerosene, fuel oil or light oil, mixed if desired, with other hydrocarbons.  Fig. 2 (not shown) illustrates a refrigerating system incorporating both coil 15 and and coil 22.

A pipe 14 upstream of the regulator 16 is connected to three control pipes 26, 28, 30 each containing a manually adjustable pressure regulator 32, 34, 36 and an electromagnetically operable control valve 38 40, 42. The regulators 32, 34, 36 are adjusted to different pressures so that by opening one of the valves 38, 40, 42 and closing the other two, a desired oxygen pressure is obtained at the cutting torches 18. When the pipes of the apparatus are to be flushed with oxygen, the valve 38 is opened; when a hole is to be pierced in or a cut produced at the edge of a workpiece the valve 40 is opened and when a workpiece is to be cut, the valve 42 is opened. The pressure is indicated by a manometer 24. At the end of the cutting process, the value 42 is closed and the vent valve 46 opened to release the control side of the pressure regulator 16 from pressure and allow it to close. A vent valve 20 at the end of the pipe 12 is opened simultaneously with or shortly after the vent valve 46.
